Este é um algoritmo bem simples.Consiste em calcular os três tipos mais conhecidos de
energia:

1-Energia Gravitacional
2-Energia Cinética
3-Energia Elástica

obs. A Energia Elétrica ficou de fora, mas logo vou incluí-la.

O usuário vai fornecendo os vários dados de entrada referente a cada tipo de energia, depois
entra em um menu para escolher qual energia calcular.
